近年来，调距桨轴内油管的故障频发已成为影响大型舰船推进系统可靠性的关键因素，深入研究油管结构的振动机理对于理解故障成因、制定预防措施至关重要，但目前在此领域的研究相对缺乏。以调距桨轴内油管为研究对象，提出一种对复杂的流-固耦合结构附加质量的计算方法，能够综合考虑流体压力与流体作用对结构的影响，并运用Hypermesh与Abaqus软件进行联合仿真，对油管结构进行精细化建模与计算。研究结果表明，这种方法在舰船轴系运转频率范围内能准确模拟声固耦合算法的结果，满足调距桨轴内油管振动分析范围；并对调距桨轴内油管支承结构优化布置和流体压力对管壁的作用进行研究，得出了调距桨轴内油管振动的规律，为调距桨轴内油管设计提供参考。
In recent years, frequent failures of the oil pipes within controllable pitch propeller (CPP) shafts have become a critical factor affecting the reliability of large ship propulsion systems. In-depth research on the vibration mechanisms of oil pipe structures is essential for understanding the causes of these failures and establishing preventive measures, yet there is a relative scarcity of research in this area. Focusing on the oil pipes within CPP shafts, a method for calculating the added mass of complex fluid-structure interaction structures has been proposed. This method takes into account the effects of fluid pressure and fluid action on the structure, and utilizes Hypermesh and Abaqus software for a combined simulation, enabling a detailed modeling and calculation of the oil pipe structure. The research results indicate that this method can accurately simulate the results of the acoustic-structure coupling algorithm within the operating frequency range of ship shaft systems, meeting the vibration analysis requirements for oil pipes within CPP shafts. Additionally, the study investigates the optimization of the supporting structure layout for the oil pipes within CPP shafts and the effects of fluid pressure on the pipe walls, revealing the vibration patterns of these oil pipes. This research provides valuable insights for the design of oil pipes within CPP shafts.
